In addition to components of WIAS, controllers of other Wärtsilä equipment can also be accesses. Combined with a service agreement, the RMS solution makes it possible for Wärtsilä employees to assist the crew in fault finding and corrections on Wärtsilä equipment 24/7. 19
BALLAST WATER MANAGEMENT SYSTEMS BALLAST WATER MANAGEMENT SOLUTIONS FOR ALL SHIP TYPES The IMO Ballast Water Convention was introduced in 2004 to address the Control and Management of Ships Ballast Water and Sediments. The regulation specifies that all sea going vessels greater than 400 gross registered tonnes need to install a Ballast Water Management System. In recognising that no one solution will be suitable across all ship types, Wärtsilä is uniquely placed to offer owners & operators a choice of Ballast Water Management Systems (BWMS). The two Wärtsilä AQUARIUS BWMS are designed to use a common filter module, and a different disinfection technology. The Wärtsilä AQUARIUS UV BWMS uses Medium Pressure Ultra Violet (UV), while the Wärtsilä AQUARIUS EC BWMS uses electrochlorination technology. 20
The Wärtsilä AQUARIUS BWMS range offers the following advantages: z Proven performance to meet D2 z Low total cost of ownership z Fully automatic operation z Condition-based monitoring optional functionality z Flexible upscaling and modular design z Suitable for both new build and retrofit projects z Technology choice By virtue of Wärtsilä AQUARIUS BWMS range modular design, the system s inherent flexibility allows application across the full range of ship types and sizes, for both the new build and retrofit markets. Wärtsilä offers customers a range of flexible supply options, from equipment only, to a full turnkey service covering all phases, from the initial survey through to the project management, supply, installation, and commissioning of the hardware, and continuing with lifecycle after sales service and support. 21
BALLAST WATER MANAGEMENT SYSTEMS Wärtsilä AQUARIUS UV Wärtsilä AQUARIUS UV Ballast Water Management Systems (BWMS) provide robust technology for the treatment of ballast water using ultra-violet (UV) irradiation, across the full range of ship operating and environmental conditions. The Wärtsilä AQUARIUS UV BWMS uses a simple two stage process involving filtration and UV irradiation. During uptake, seawater is first passed through a 40 micron backwashing screen to remove particulate, sediment, zooplankton and phytoplankton. Disinfection of the filtered sea water is then carried out using medium pressure UV lamps, and controlled by the BWMS control system. Upon discharge, the filter is by-passed but the ballast water is again disinfected with UV treatment before safe discharge back into the sea. The system has a modular design enabling it to be arranged to suit conditions onboard the ship. The system can be designed and 22

BALLAST WATER MANAGEMENT SYSTEMS Wärtsilä AQUARIUS EC Wärtsilä AQUARIUS EC Ballast Water Management Systems (BWMS) provide robust technology for the treatment of ballast water using insitu electro-chlorination, across the full range of ship operating and environmental conditions. The Wärtsilä AQUARIUS EC BWMS uses a simple and efficient two stage process involving filtration and electro-chlorination (EC). During uptake, seawater is first passed through a 40 micron backwashing screen filter to remove particulate, sediment, zooplankton and phytoplankton. Disinfection of the filtered sea water is then carried out using hypochlorite generated from the side stream EC process, and controlled by the BWMS control system. Upon discharge, the ballast water by-passes the filter and any residual active substance is neutralised using sodium bisulphite, to ensure that the ballast water is safe to discharge back to the sea in full compliance with MARPOL requirements. 24

ENGINES AND GENERATING SETS Definitions and Notes for Low-Speed Engines ISO standard reference conditions Total barometric pressure at R1...1.0 bar Suction air temperature...25 C Relative humidity...30% Cooling water temperature before engine...25 C Emissions All Wärtsilä low-speed engines included in this booklet are fully compliant with IMO Tier II NO X limits specified in Annex VI of the MARPOL 73/78. They can also be equipped with a SCR catalyst to meet IMO Tier III NO X emission levels and a scrubber to reduce SO X emissions to 0.1% even with high sulphur fuels. Rating points for Wärtsilä low-speed engines The engine layout fields for Wärtsilä low-speed engines are defined by the power/speed rating points R1, R2, R3 and R4 (see diagram to the right). In certain engines, the layout field is extended to the points R1+ and R2+. 56
R1, or R1+ instead if applicable, is the nominal maximum continuous rating (MCR). Any power and speed within the respective engine layout field may be selected as the Contract-MCR (CMCR) point for an engine. Cylinder lubrication The Pulse Lubricating System with electronic control of lubrication timing has been further developed, giving important savings in engine Power LOW-SPEED ENGINES Engine layout field Engine-MCR R1 R1+ Speed operating costs. The guide feed rate for new engines equipped with the Pulse Jet cylinder lubrication system is 0.6 g/kwh. Engines with different lubricating systems might require a higher feed rate.

ENGINES AND GENERATING SETS Dimensions and weights z All dimensions are in millimetres and are not binding. z F1: Min height for vertical removal z F2: Min height for vertical removal with double-jib crane z F3: Min height for tilted removal with double-jib crane z The engine weight is net in metric tonnes (t), without oil and water, and is not binding. Fuel consumption All brake specific fuel consumptions (BSFC) are quoted for fuel of lower calorific value 42.7 MJ/kg, and for ISO standard reference conditions (ISO 15550 and 3046). For all Wärtsilä low-speed engines stepwise tolerances have been introduced for the brake specific fuel consumption (BSFC): z +5% tolerance for 100% to 85% engine load z +6% tolerance for 84% to 65% engine load z +7% tolerance for 64% to 50% engine load The BSFC guarantee is possible at several load points between 50 100%. Standard Tuning, Delta Tuning, Delta Bypass Tuning and Low- Load Tuning are available for the electronically-controlled common-rail engines to provide optimum fuel consumption and flexibility for different engine loads. Delta Tuning focuses on reducing fuel consumption in the operating range below 90% engine load. Delta Bypass Tuning provides increased steam production between 50 and 100% engine power. Low- Load Tuning reduces fuel consumption below 75% engine load. Dual tuning is available on request and in cooperation with Classification Societies.

LOW-SPEED ENGINES Exhaust gas economizer Steam turbine Ship service steam Ship service power Turbochargers Motor/generator Exhaust turbine Aux. engines Main engine Schematic of a High-Efficiency Waste Heat Recovery plant typical for large container ships. High-Efficiency Waste Heat Recovery (WHR) Waste heat recovery is an effective technology for simultaneously cutting exhaust gas emissions and reducing fuel consumption. High- Efficiency Waste Heat Recovery plants can be installed with Wärtsilä engines. This enables up to 12% of the main engine shaft power to be recovered as electrical power for use as additional ship propulsion power and for shipboard services. These WHR plants thus cut exhaust gas emissions and deliver fuel savings of up to 12%. Steam based WHR has already been successfully fitted in several installations to Wärtsilä low-speed marine engines. In the WHR plant, a turbo-generator combines input from a steam turbine and an exhaust gas power turbine to generate electrical power, while steam from the economiser is available for ship service heating. Steam based WHR is recommended for vessels with high installed power. 59

EXHAUST GAS CLEANING EXHAUST GAS CLEANING Due to existing regulations on emissions to air from the International Maritime Organisation (IMO), and with the European Union working towards an alignment with IMO MARPOL Annex VI, marine industry operators need to decide on the best means for achieving compliance. Wärtsilä exhaust gas cleaning technology is an economical and environmentally friendly solution for tackling all new and existing rules and regulations. The systems are suitable for both new buildings and the retrofitting of existing vessels having either 2-stroke or 4-stroke engines, as well as for oil-fired boilers. Our new inline scrubber system design is also a more compact offering saving considerable space and cost, installation is faster and easier, and operational flexibility is improved. The design is applicable for our Hybrid and Open Loop Scrubber Systems. Having the largest installed base of any marine scrubber supplier and a dedicated test laboratory has enabled Wärtsilä to optimise their products to be reliable, easy to operate, and easy to install. Wärtsilä Hybrid Scrubber System Wärtsilä provides hybrid solutions which have the flexibility to operate in both open and closed loop using seawater to remove SO X from the exhaust. When operating in open loop, exhaust gases enter the system and are sprayed with seawater. The sulphur oxides in the exhaust react with the water to form sulphuric acid. Chemicals are not required since the natural alkalinity of seawater neutralizes the acid. When operating in closed loop, the natural alkalinity of seawater is boosted by an alkali. 84
Wärtsilä Open Loop Scrubber System Our scrubber system is based on the same technology as that used in Wärtsilä s inert gas systems for more than 50 years. The system operates in an open loop utilising seawater to remove SO X from the exhaust. Exhaust gas enters the scrubber and is sprayed with seawater in three different stages. The sulphur oxide in the exhaust reacts with water and forms sulphuric acid. Chemicals are not required since the natural alkalinity of seawater neutralises the acid. Wash water from the scrubber is treated and monitored at the inlet and outlet to ensure that it conforms with the MEPC 184(59) discharge criteria. It can then be discharged into the sea with no risk of harm to the environment. 85
EXHAUST GAS CLEANING Wärtsilä Closed Loop Scrubber System The system operates in a closed loop, i.e. the wash water is being circulated within the scrubber. Exhaust gas enters the scrubber and is sprayed with fresh water that has been mixed with caustic soda (NaOH). The sulphur oxides in the exhaust react with this mixture and are thereby neutralised. A small bleed-off is extracted from the closed loop and treated to fulfil requirements stipulated by the IMO. Cleaned effluents can be safely discharged overboard with no harm to the environment. If operation in zero discharge mode is requested, the effluent can be led to a holding tank for scheduled and periodical discharge. ØD Øout E U Øin H C B ØP 86

GAS SYSTEMS Wärtsilä Hamworthy Flare Gas Recovery The Wärtsilä technology safely captures and handles flare gas, which can then be re-utilised for other purposes. Flaring gas emits some 400 million tons of CO 2 annually to the atmosphere, and has a notable impact on the environment. The Wärtsilä Hamworthy Flare Gas Recovery system offers a substantial reduction in such emissions. It allows the previously flared gas to be available for re-utilisation as fuel or export gas re-injected, as feed for boilers, and for many other gas related applications. The closing of the flare line during normal operations results in significantly decreased flare tip wear, allowing it to typically last for the lifetime of the field. The concept comprises flare header isolation equipment, a gas recovery system, and a reliable flare gas ignition system. Our systems can be designed to meet the specific process conditions of the plant. 90
GAS RECOVERY Wärtsilä Hamworthy Flare Gas Ignition The Wärtsilä Hamworthy Flare Gas Ignition system ensures the safe and reliable ignition of the flare whenever required. Our system is suitable for all flare tips and may ignite several flares on a single flare deck. It is installed at a safe distance from the flare stack, with a guide pipe leading to the flare tip. The system combines high reliability and availability over the lifetime of the facility with low maintenance requirements, and is easily retrofitted into existing installations. Pilot burners are not necessary, and there is no heat sensitive equipment, such as cables, instrumentation and electrodes, on the flare deck. 91
GAS SYSTEMS Our Hydrocarbon Gas Blanketing Systems are already used onboard numerous projects in the North Sea and West Africa. Wärtsilä Hamworthy Hydrocarbon Blanketing Systems Wärtsilä Hamworthy s Hydrocarbon Blanketing System eliminates the environmental damage and economic loss caused by emissions of gas vented to the atmosphere in a conventional process This Wärtsilä system utilises hydrocarbon gas as a blanket gas in the cargo tanks, and recovers the off gas. Its primary application is in FPSOs. The blanket gas prevents the intrusion of oxygen into the cargo tank atmosphere, thus creating a closed system. During loading, surplus gas from the cargo is recovered and recycled into the process plant by means of a blower/ejector/compressor. When offloading, the hydrocarbon blanket gas is supplied to maintain pressure in the cargo tanks. All the hydrocarbons are recovered to the process, and emissions into the atmosphere are eliminated during normal operation. 92
GAS RECOVERY The first VOC condensation system with zero emissions was installed on the shuttle tanker Stena Alexita, operated by ExxonMobil in the North Sea oil fields. Wärtsilä Hamworthy VOC Recovery Our field proven VOC recovery system is self supplied with energy and results in zero Volatile Organic Compounds (VOC) emissions. These emissions from the global sea transportation of crude oil and associated products, account for a total of more than 5 million tonnes per year. The Wärtsilä Hamworthy VOC plant ensures that cargo tank pressures are maintained low enough to keep the vent valve closed. This prevents VOC from being emitted to the atmosphere, and the gas is instead fed to the VOC recovery module, where it is treated by compression and condensation. The liquefied gas is then fed to the VOC fuel tank. We have also developed a system for VOC recovery in offshore oil loading applications. It exceeds the Norwegian authorities requirements for Non-Methane Volatile Organic Compounds (NMVOCs) by reducing VOC emissions by 100 per cent, including methane, which is not currently specified in the regulatory requirements. 93
GAS SYSTEMS Wärtsilä GasReformer This solution makes it possible to utilise gaseous fuels that either contain large amounts of heavier hydrocarbons or vary in their composition. Gases that were previously considered as waste can now be converted into a valuable resource of energy. Together with Wärtsilä dual-fuel (DF) engines, this is the most efficient and flexible solution for utilising associated gas, stranded gas, natural gas liquids, LPG or volatile organic compounds (VOCs) recovered from oil and gas industry. The main application area is in offshore oil and gas production. Wärtsilä GasReformer has been developed and designed to meet the standards of the oil & gas industry and is the first of its kind in the world. The technology is based on steam reforming (SR), a catalytic process known from the petrochemical industry and refineries, where traditionally hydrogen is produced from various hydrocarbon feeds. The Wärtsilä GasReformer exploits the same catalytic process but operates under different conditions. In the Wärtsilä GasReformer the methane number (MN) of any fuel gas is improved to 100 ± 5 by converting the heavier hydrocarbons to synthesis gas (H 2 + CO) and finally to methane (CH 4). 94
Environmental excellence Offshore gas flaring is increasingly recognised as a major environmental problem, causes 400 million tons of CO 2 in annual emissions, not to mention the valuable resources that go to waste. The associated gas, separated from crude oil, is traditionally flared and not utilised because it varies in composition, and contains a lot of heavier hydrocarbons. Generally it is considered as waste or an unreliable source of energy. With the Wärtsilä GasReformer, this undesired gas can be reliably and efficiently utilised by Wärtsilä dual-fuel engines. When utilising associated gas or recovered VOCs as a reliable source of energy, the operator can achieve self-sufficiency in terms of energy supply and thus the need for fuel bunkering, a costly operation in offshore locations, decreases. With an 8 MW Wärtsilä GasReformer combined with a dual-fuel engine utilising associated gas, the operator can reduce the need for bunkered fuel oil by about 35 39 tons per day. With a Wärtsilä DF engine the system produces electricity with an overall efficiency of up to 44.5%. Key benefits z Reduction of CO 2 and VOC emissions z Flare gas can be utilised for power production z No need for flaring z Reduced fuel consumption and fuel bunkering z Low NO X emissions from proven dual-fuel engines z Dual-fuel engines can operate at full load and efficiency z Operator can change gas source during operation z Decreased carbon footprint for operating company Product Specification per 1 MW shaft power of DF engine Pressure (design) 7 10 (11) barg Temperature (design) 300-420 (500) C Feed gas (MN 50) mass flow rate 189 kg/h/mw Feed gas volumetric flow rate 176 kg/h/mw Total steam demand of which recycled condesate water of which fresh water 220 kg/h/mw 170 kg/h/mw 50 kg/h/mw Cooling demand 150 kw/mw Dimensions (mm) and weights (tonnes) GasReformer capacity Lenght Width Height Weight GAS RECOVERY El. heater, max (kw) Nitrogen consumption start-up (shut-down) 4 MW 5000 3000 3000 15 30 5 (20) Nm 3 8 MW 5800 3500 3500 18.5 100 6 (27) Nm 3 18 MW 7000 4800 4200 40 250 15 (60) Nm 3 95
GAS SYSTEMS Wärtsilä LNGPac Natural gas is becoming increasingly viable as a propulsion fuel in marine applications. Wärtsilä is a leader in developing dual-fuel engine and LNG fuel system technologies that have enabled this change. We offer the LNG fuel system on its own, as well as a part of a complete propulsion system. Wärtsilä can deliver LNG fuel gas systems for propulsion and power generation for any applicable types of ship or engine. Standard solution Bunkering takes place from the bunkering station to the LNG tank via an insulated pipe. The LNG tank connection space compartment is mounted directly on the LNG tank. The tank connection space contains all the piping penetrations through the tank shell, as well as all heating media connections to the LNG evaporators. The process inside the tank connection space includes all the connections and valves between the tank and the Pressure Build-up Evaporator (PBE), and between the tank and the Main Gas Evaporator (MGE), together with the evaporators themselves. The evaporators are heated by glycol-water that is circulated within a glycol-water heating unit. Wärtsilä is proposing as a standard a proven design with no rotating machine with a pressurised vacuum insulated tank type C. 96

LNG HANDLING We have delivered and put into operation numerous floating LNG regasification plants based on either closed loop regasification technology, using steam with water/glycol as the intermediate heating medium, or open loop regasification technology using sea water with propane as the intermediate heating medium. We have also delivered modularised regasification plants for jetty installations. These facilitate a much shorter construction time compared to the traditional land based LNG regasification terminal project. Wärtsilä Hamworthy LNG Reliquefaction Wärtsilä is an established leading designer, developer, and supplier of energy efficient LNG Boil-Off Gas (BOG) reliquefaction plants that are reliable, safe, robust and flexible. Wärtsilä has by far the highest number of BOG reliquefaction plants installed in the global LNG carrier fleet. They offer owners and operators unsurpassed lifecycle efficiency, and are backed by a full range of complementary services, including operation & maintenance training, remote monitoring & diagnostics, and customised service and support agreements. Wärtsilä has commercialised and improved reliquefaction technology since it was originally patented by Kværner and licensed by Hamworthy in the late 1990s. Our boil-off gas (BOG) reliquefaction plants have been installed on numerous vessels, including the entire Q-Flex fleet of 216,000 m 3 LNG carriers. The 31 Wärtsilä Hamworthy LNG BOG reliquefaction plants delivered to the Q-Flex fleet are installed on ships driven by slow speed diesel propulsion engines. The process is based on the reversed nitrogen Brayton cycle refrigeration technology, combined with a process solution for separating nitrogen from the BOG. We have also delivered the same type of systems to a number of LNG carriers with dual-fuel diesel electric (DFDE) propulsion. The liquefaction of BOG on LNG carriers results in increased cargo deliveries, and allows owners and operators to choose the optimal propulsion system and operating profile. We work closely with our customers to develop technological solutions that meet their needs for increased fuel flexibility, energy efficiency, and environmental performance in today s fast changing LNG market. 99

GEARS WÄRTSILÄ GEARS Wärtsilä gears have been designed to meet the highest standards of operational efficiency, reliability and low noise and vibration. Gear configurations z Single input gears: gears with single input and single propeller speed. Wärtsilä designation SCV for vertical offset, and SCH for horizontal offset. Available with or without clutch. z Double gears: gears with twin input and single propeller speed. Wärtsilä designation TCH. z 2-speed gears: gears with single input and 2 propeller speeds. Wärtsilä designation SCV/2 for vertical offset, and SCH/2 for horizontal offset. All Wärtsilä gears can be supplied with built in multi-disc clutches. Power take-off (PTO) All Wärtsilä gears can be supplied with one or more PTOs for driving the shaft alternator, compressor or pump. For single vertical and horizontal gears, the standard PTO is primary driven. For double gears, the PTO is optionally primary or secondary driven. z A primary driven PTO is rotating whenever the engine is rotating. z A secondary driven PTO is rotating whenever the propeller shaft is rotating. Power take-in (PTI) Most Wärtsilä gears can be supplied with a combined PTO/PTI. In PTI mode the shaft alternator can also be used as an electric motor. PTI is normally used for the following operation modes: z PTI Booster mode is used when the main power of the engine is too small, in order to increase the total propulsion power. For this mode, no clutches are required on the gear. z PTI Take me home mode is used in case of emergency, if the prime mover is out of operation. For this mode a minimum of 2 clutches are required on the gear. Integrated or separate hydraulic system for gear and controllable pitch (CP) propeller Most Wärtsilä gears are purpose-designed with an integrated hydraulic system for both the gear and the CP propeller. As the separate hydraulic power unit for the CP propeller is superfluous, both installation costs for the yard and operational costs for the owner are reduced. For safety reasons the gear mechanically drives the main pump for the propeller. All gears can also be interfaced to a separate hydraulic power unit. 108
Wärtsilä 2-speed gear The Wärtsilä 2-speed gear is designed to serve vessels having multiple operational modes or reduced transit speed. In particular, RoPax ferries, offshore support vessels, tug boats and fishing vessels can gain notable economic and environmental benefits. Also single screw vessels with redundant propulsion system ( take me home system ) will benefit from this gear type. By operating the ship s propeller at low speed when maximum vessel speed or propeller thrust is not required, fuel consumption can be reduced by as much as 15 percent compared to a single mechanical propulsion system. At the same time, nitrogen oxide (NO X) and sulphur oxide (SO X) emissions are similarly lowered. Benefits z Fuel consumption and exhaust gas emissions reduced z Reliable performance with low transmission losses z Acts as a systems enabler for vessels with variable operational modes and/or a need for a redundant propulsion system z Two selectable propeller speeds at 100% engine speed z Provides efficient utilisation of the main engine z PTO power 100% of the engine power z PTO power uninterrupted when changing propeller speed z Reliable and simple to operate with mode changes from the bridge z Lower noise levels for onboard comfort and ecological friendliness 109

Wärtsilä iphase The Wärtsilä iphase profiler measures the oil-water interface, providing accurate measurements of water conductivity and thereby the oil in water profile inside hydrocarbon separators. Several independent sensors are located above each other in order to measure a vertical profile of the separator contents. Each sensor measures the bulk properties of the surrounding fluid. The measurement is conducted without electrodes and over a large volume which makes it less sensitive to deposits. The Wärtsilä iphase electronic module is located on the top of the separator vessel and is connected to the Wärtsilä iphase Measurement Rod, located inside the vessel. It performs all calculations onboard and can directly be accessed by the plant control system via MODBUS RTU or 4 20 ma signaling. Measurement principle The Wärtsilä iphase profiler measures the electrical conductivity of the water/oil mixture surrounding each sensor. Dispersed oil droplets are non-conductive compared to the surrounding water. The overall conductivity will therefore decrease with increasing concentration of oil. The Wärtsilä iphase sensors utilize the conductivity difference to measure the oil in water content. The conductivity is measured by setting up an electric field and measure the current flowing. The electric field is an induced field and is therefore very tolerant to deposits. Features z Inductive measurement principle z Tolerant to deposits z High accuracy oil/water interface determination z Separator water profiling z Detection of sand build-up z Integrated temperature sensor z Intrinsically safe electronics z No active components inside vessel z Control system interface MODBUS RTU (RS485) z 4 20 ma for interface signaling z Certifications: ATEX Ex ia IIB T4, IECEX, EMC, UL z No export restrictions 123

Wärtsilä passive rectifier The Wärtsilä Power Drive can be delivered with a diode rectifier in a 12, 18 or 24 pulse configuration, very well suited to either a Wärtsilä LLC system or a standard transformer solution. Wärtsilä active front end rectifier The Wärtsilä Power Drive can also be delivered with an active rectifier front end which allows for energy flow in both directions, eliminating the need for transformers and braking resistors. Direct Current Control and a network filter give small ripple currents and very low harmonic distortion well below international standards. Multidrive systems, DC sources The Wärtsilä Power Drive can also be delivered as a multidrive system, where the inverters are connected to the same DC-link. Combined with our patented electronic DC breakers, these work independently. The multidrive system can be connected to the main grid through either active or diode rectifiers, and can also allow for DC-sources such as batteries and fuel cells.

PROPULSORS Photo courtesy of Austal WATERJETS Waterjet propulsion is the most successful and efficient method of propulsion for vessels having speeds in excess of 30 knots, or where there is a likelihood of the vessel operating in shallow waters where propulsors protruding from the hull cannot be used. Wärtsilä has successfully installed waterjets in various high-speed vessels, landing craft and other applications that require shallow water access, high manoeuvrability or low noise and vibration levels. In addition, Wärtsilä s Waterjet and Refined Propeller (WARP) system offers a solution for craft with a versatile operating requirement of around 30 knots. Usually about one third of the total vessel power is linked to two propellers with the rest of the power used for the central boost waterjet. The advantage is a reduced vessel draft with an optimised propeller diameter for efficient cruising at around 20 knots. For top vessel speeds of around 30 knots, the propellers and the waterjet are designed to jointly achieve the thrust required. Wärtsilä is a market leader in WARP systems with several Navy, Ferry and Yacht applications in operation with both controllable & fixed pitch propeller waterjet combinations. 156
WATERJETS Waterjet Types Wärtsilä has a unique portfolio of waterjet types available. The right waterjet for your application will be selected based on the operating profile and the required ship interface. The operating profile will determine the type of pump to be selected. For high power dense, high speed applications above 50 knots, a non-axial E-type pump design is available, delivering optimal performance for extreme vessels. For applications that require optimum propulsion efficiency for design speeds below 45 50 knots, our axial geometry waterjet designs are the perfect answer. Our axial waterjet design is the most compact and most lightweight waterjet design available in the full stainless high-end waterjet market, offering extra thrust and manoeuvring properties at the low end of the speed range for top acceleration. Plug and Play Wärtsilä Midsize Jet For ease of installation with minimum ship interfaces, waterjet sizes up to the 810 can be delivered in an easy install package with all auxiliary systems pre-mounted. The waterjet inlet duct is included in the scope of supply with impeller shaft and bearings delivered prealigned on a ready-to-install skid. The design has all oil-lubricated or oil-containing parts mounted inboard of the vessel, and it is the The most compact, easy to install waterjet package available on the market with a stainless steel impeller and a unique stainless steel stator section for top vessel performance long after the initial newbuild sea trials. Other system materials are optimised for use with lightweight aluminium or composite crafts. 157
PROPULSORS only easy install waterjet package on the market with a compact steering and reversing assembly not extending outside the transom mounting flange diameter. Aluminium materials are avoided for the stator bowl, and the full stainless stator section with the stainless impeller and shaft provides optimum resistance against abrasive wear of the stator blades. Deterioration of the stator blade profile should be avoided wherever possible, since they play an important role in the largest energy transformation taking place in a jet system. For vessels requiring top performance also long after the initial newbuild sea trials a stainless stator section will deliver real added value.

WATERJETS Waterjet size selection The graphs below indicate the jet size required based on the relation between the engine power and the design speed of the vessel. For instance a ship with four 1250 kw engines and a corresponding vessel speed of 33 knots will need four 510 size waterjets. A ship with a design speed of 40 knots at 1250 kw power can use 450 size waterjets. The correct jet size is thus indicated by the line above the intersection of the power and the corresponding vessel speed (see examples in the graphs below). We are available from the earliest design stages of the vessel to work with you on an optimised propulsion system. Please contact us for an optimised jet selection based on specific vessel design parameters, operating profile or for details of waterjets above 50 knots or 30 000 kw. DXF/DWG format general arrangement drawings of the most often used sizes are available.

NOZZLES AND RUDDERS Wärtsilä High Performance Nozzle Fitting a nozzle increases the thrust at relatively low ship speeds. Significant savings can be achieved in terms of fuel consumption, depending on the number of revolutions and the capacity of the engine. The improved Wärtsilä High Performance nozzle, type HPN, combined with Wärtsilä propellers, can provide up to 5% more thrust than conventional nozzles in bollard pull condition. The nozzle profile offers a double profiled cross section at the inlet side of the nozzle. Energopac Rudder Energopac is the optimised propulsion and manoeuvring solution for coastal and sea going vessels. The key objective is to reduce the vessel s fuel consumption by integrating both propeller and rudder design. Each Energopac is designed to fit the vessel and to meet its specific requirements; this allows Energopac to be optimised fully for energy efficiency, whilst not compromising on either manoeuvrability or comfort levels. Fuel savings Energopac reduces fuel consumption because it reduces flow separation behind the propeller hub in an effective way. Extended 162
studies show that for the same course-keeping capabilities, Energopac will create less drag than conventional rudder systems. Especially when using small corrective steering forces to keep your vessel on course, the difference in rudder resistance is significant. The high-lift performance of Energopac requires smaller steering angles and consequently reduces rudder resistance. Design space The application of Energopac gives more freedom to create high efficiency from conflicting requirements. High performance propeller designs are often a compromise between increased efficiency and reduced vibration levels. Energopac allows for a propeller design, that gives the optimal balance between these requirements. Typical applications Energopac will effectively reduce the operational costs for any vessel with a considerable share of free sailing time in its operational profile. Additionally, it will work very well for propellers with a relatively large propeller hub. The potential savings are large for vessels with highly loaded controllable pitch propeller systems, such as RoRo-vessels, ferries, container / multipurpose vessels, and vessels with an ice class notation. Cost savings with Energopac The reduction in fuel consumption depends very much on the vessel type, the operational profile of the vessel, and also on the reference propeller and rudder. For any application, the power savings can be estimated by Wärtsilä. The estimate is based on the vessel design, operational profile and other requirements. Proven savings in required power for a vessel s trial speed vary between 2 9% with Energopac. 163

PUMPS Wärtsilä Svanehøj Portable Pumps Wärtsilä Svanehøj hydraulically driven portable pumps are widely used in oil product and chemical tanker applications. Our single-stage centrifugal portable pumps are mounted with mechanical shaft seals and a hydraulic motor, built together in an acid-proof housing and protected in such a way that the pump stands submersion into most liquids. The hydraulically driven portable cargo pumps have an outer diameter that is less than a standard 12 butterworth hatch and can, therefore, be submerged into the cargo tank. The pumps can be connected either to the ship s hydraulic system or to a hydraulic power pack unit via a ring line. They are easy to connect using quick couplings, while the manoeuvring of the pump by a flow regulating valve makes for fast and trouble-free handling Wärtsilä Hamworthy Offshore Booster Pumps For FPSO s and FSU s where higher discharge presures are required due to e.g. unloading via a remote bouy, a separate Booster Skid can be applied on the forward part of the vessel. This has been a popular and successful application on our deliveries for conversions of ex. seagoing Tankers as the original piping can be utilized all the way up to the Booster Skid. The Booster Skid can be combined with both Deepwell Cargo Pumps and traditional Pump Room System. 166
The actual Booster Pumps are in-line heavy duty centrifugal pumps with dual suction impeller and double vulute casing assuring both axial and radial balance, and in order to handle the inlet pressure from main cargo pumps we have developed a special balanced mechanical seal arrangement for this purpose. Wärtsilä Hamworthy Deepwell Offshore Process and Cargo Pumps For FPSOs/FSOs requiring a distributed pump system, the Wärtsilä Svanehøj range of electrically driven deepwell pumps represents an efficient and cost effective crude handling system. In providing the long term benefits of lower maintenance and less downtime, our deepwell pumps also use less energy than other comparable distributed pump systems. Our shaft lubrication system enables less onboard maintenance to the electric system. The pump housing is easily dismantled, and cards on the converters are easily interchanged. During the operational phase, the electrical equipment offers environmental sustainability, since CO 2 emissions are minimal due to the higher efficiency and lower power utilisation, and there is no risk of hydraulic oil spills. Wärtsilä Svanehøj deepwell process and cargo pumps are designed for continuous operation with pumping mediums such as crude oil and produced water and oil. The type OPC pumps can be delivered according to API 610, and are designed with a capacity from 20 1800 m 3 /h. 167

WASTE, OIL & FRESH WATER MANAGEMENT FRESH WATER GENERATION Wärtsilä Serck Como s well-proven, multi-stage flash (MSF) principle is the most reliable thermal seawater desalination process in the world and is the only evaporation principle where heat transfer and evaporation are strictly separated. Utilising its experience since its foundation in 1841 in Germany, Wärtsilä Serck Como designs and manufactures multi-stage flash desalination plants which are employed for producing fresh water from sea water, well water or industrial water. A special advantage of the multi-stage flash technology is that the specific heat consumption (or thermal efficiency) can be continuously adapted to the individual requirements of each cruise vessel. We also offer multiple effect evaporators which are individually designed to the customer s specific requirements, plate type evaporators which utilise the waste heat from the main diesel engine jacket water, and rising film evaporators which are shell and tube type, single-stage units. 186
Wärtsilä has developed an energy efficient and cost-effective technology for sea water desalination, with a capacity up to 30 t/d, for marine and offshore application. Wärtsilä Serck Como s fresh water generator uses the process of vacuum distillation to remove the salt and other impurities from seawater and convert into high quality, drinkable fresh water. Due to the use of a low seawater flow Wärtsilä Serck Como s fresh water generator consumes a reduced amount of electricity. Developed in Wärtsilä s plant in Geesthacht, Germany the system uses a vacuum distillation process which enables the usage of heat at low temperatures. The generator utilises the waste heat from the main diesel engine or other alternative heat sources to evaporate the seawater. The technology is simple and has a modular design. The automated operation and the low maintenance efforts enable continuous and user friendly handling. 187
WASTE, OIL & FRESH WATER MANAGEMENT OILY WATER SYSTEMS Wärtsilä Oily Water Separator The Wärtsilä oily water separator (OWS) gives the operator effective control over all bilge and sludge media as well as over any discharges made into the sea. The technology behind the Wärtsilä OWS is a combination of optimised traditional methods and innovative new solutions. The separator consists of a four-stage, emulsion-breaking unit, in which each stage handles one key component of the sludge and bilge mix. It can handle input flows with an oil content of between 0 and 100%, making it the most versatile separator on the market. All Wärtsilä units have successfully passed USCG / IMO type approval in accordance with 46 CFR 162.050 and MEPC.107(49). The amount of oil in the water after treatment is guaranteed to be less than 5 ppm.

Wärtsilä Bilge Water Guard The Wärtsilä Bilge Water Guard (BWG) is a fully automated, bilge discharge monitoring system which constantly oversees and monitors the oil content in all discharges overboard. Should the oil content rise above the set limit, the flow will be re-routed back to the bilge tank. The system logs the discharge quantity and oil content as well as time and location of the ship. All data is stored in memory for later retrieval. The system is enclosed in a locked, tamper-proof cabinet and all accesses are logged in memory. For both crew members and ship management, the Wärtsilä BWG provides a priceless safety net that makes compliance with the applicable regulations evident. Wärtsilä Oily Water Treatment Wärtsilä Oily Water Treatment (OWT) unit is a compact unit for Power Plants. In the oily water treatment unit the oily water is treated to clean the water fraction in order to allow its discharge to the nature while separated bottom solids and lighter oily sludge is pumped to the sludge tank. The disposal method for the oily water or sludge should be environmentally acceptable. Typically special disposal companies or local industry are used, if approved by the authorities. 189
WASTE, OIL & FRESH WATER MANAGEMENT Wärtsilä Slop Water Treatment Wärtsilä Slop Water Treatment system is designed to clean mud or water (deck washing water or rain) contaminated with slop or drilling mud from offshore units particularly drilling rigs and drilling ships. The unit will significantly reduce drill slop sent onshore for treatment by as much as 80 90%. The system s processing principles are based on a combination of chemical treatment and dissolved air flotation. The chemicals flocculate and bind together particles, making them easier to separate, which then allows flotation by dissolved air to separate both particles and oil from the water. The result is clear water, free of particles and oil, and acceptable for discharging into the environment or for reuse on the rig. The discharge is monitored by an in-line, oil-inwater content meter that ensures that the oil in the water is below the required limits before the water is pumped overboard. 190
ADVANCED WASTE WATER PROCESSING Wärtsilä Hamworthy Membrane Bioreactor (MBR) Systems Wärtsilä s innovative MBR system is an evolution of the company s proven sewage treatment technology for handling grey and black water waste. The technology is an advanced wastewater treatment process based on biological degradation and membrane separation. It delivers the highest quality discharge without requiring the generation or addition of chemicals hazardous to the maritime or shipboard environment. Wärtsilä Hamworthy minimbr Systems Wärtsilä minimbr systems are smaller, more compact versions of the company s innovative MBR technology for handling grey and black water waste. By building on our successful experiences and working closely with our customers, we have been able to optimise the minimbr system to produce an effective compact package. It is ideal for use on smaller cruise and naval vessels, plus ferries with up to a 200 complement, as well as FPSOs and accommodation platforms. 191
WASTE, OIL & FRESH WATER MANAGEMENT WASTE WATER PROCESSING Wärtsilä Hamworthy Sewage Treatment Plants Wärtsilä is the world s leading manufacturer of marine sewage treatment systems. Wärtsilä sewage treatment plants offer easy-toinstall, trouble-free systems for some of the harshest environments on the planet and have been designed to meet existing and future IMO standards. Our sewage treatment plants are certified to meet the latest IMO MEPC 227(64) and IMO MEPC 159(55) guidelines for vessels wishing to or continuing to discharge at sea, and are recognised by leading shipbuilders. 192
VACUUM SYSTEM TECHNOLOGY Wärtsilä Vacuum Collection System The Wärtsilä vacuum collection system uses differential air pressure to transport sewage from the toilet bowls, and other sanitary fittings, to the Sewage Treatment Plant (STP) or independent collection tank. Ejectors can be mounted direct to the STP for modular construction without the need for a separate collection tank, and only a small amount of flush water is needed compared to conventional gravity systems. Wärtsilä Vacuum Toilets Wärtsilä toilets use vacuum to deliver waste from the toilet to the treatment tank or intermediate collection tank. This contemporarily styled toilet has a built-in vacuum breaker and flush memory, is simple to install, and is supplied ready to connect. The control mechanism can be accessed without removing the bowl. By using only approximately 1 litre of water, the amount of wastewater is dramatically reduced. 193

Solutions Comparison Tools Wärtsilä has established a new approach to the lifecycle of a vessel by being involved at all stages, from the initial ship design to new buildings or repowering of the complete propulsion system, and finally providing support services for the ship. Essential to effective lifecycle performance is the efficiency of the propulsion system. According to Wärtsilä, everything starts from the interaction between the hull and the propulsors. Significant savings can be achieved by optimising the propeller design and matching it with the prime movers. Engine selection is another key element in improving overall efficiency. Wärtsilä offers configurations that allow engines to run at or close to optimum efficiency. These propulsion packages are developed according to the mission profile of the vessel, as defined by the end-user. Wärtsilä develops solution comparison tools where solutions can be compared in terms of fuel consumption, emissions, investment cost, payback time, and profitability. We can help customers to select the solution that best meets their needs, taking into consideration the ship operation profile and the selected machinery concepts. 194

The trends that are shaping the marine and offshore industries business environments are creating a demand for more complex and sophisticated vessels. There is an increasing preference for full diesel electric, hybrid propulsion systems, and dual-fuel electric (LNG fuelled) vessels. These systems offer more flexibility, a higher level of redundancy, and a reduction in both fuel consumption and emissions. More advanced vessels require an integrated approach to vessel design and the configuration of the propulsion systems to ensure optimal performance and lifecycle efficiency. The more sophisticated the vessel design, the more complex are its systems. There are more interfaces between the various components, and good co-ordination between them is essential for a successful new building project. This inevitably means that in order to avoid added risk and building delays, an experienced systems integrator is absolutely essential. The choice of Wärtsilä, as a single supplier for the design, engineering, and systems integration of the main equipment, will ensure an optimised solution. This will also provide better risk control during the new building phase. Expertise BRAINWARE PROCESS Excellence 197
